PERTH (miningweekly.com) – ASX-listed Aditya Birla on Wednesday said that it would offer voluntary redundancies to certain employees at its Nifty copper mine, in Western Australia, as it worked to conclude investigations into a sinkhole.

The Department of Mines and Petroleum (DMP) in March issued Aditya Birla with a notice prohibiting all mining operations at Nifty after the sinkhole was discovered.

The miner was currently progressing its two-phased investigation into the sinkhole, and had been granted permission by the DMP to proceed uninterrupted with the second phase of drilling, which would involve the further probing of the aquifer, the sinkhole and the potential stope voids above the stope backs.

The objective of the phased drilling was to determine the extent of risks associated with the sinkhole to the bottom of the mine.

Aditya Birla said that the preliminary results from its first phase of drilling have indicated that the aquifer intersections had low seepage water, which was well within the installed pumping capacity and indicated that water inrush risk was relatively low.

The results also indicated that the sinkhole consisted of dirt, with no voids or presence of water, and both the sinkhole and the aquifer were at forecast distance from existing mine excavations.

The Phase 1 drilling was set for completion at the end of May.
